My finance director Andy just shared something I knew you’d want to hear: The Koch brothers’ Americans for Prosperity is spending $196,000 more for another week of attacking me on TV, taking the total to $679,675 – and they're now up on radio too.

The GOP, Wall Street and Big Oil are wasting no time in coming for me – it's only January, and we're already being outspent 4 to 1. They’ll all do or say anything to take the Senate and control all of Congress, which is why it’s so important we fight back now.

Andy says we need $17,500 by midnight tomorrow to keep pace with the attacks and stay on track to build a strong, grassroots-powered campaign. With the attacks getting worse every day between now and Election Day, I need your help right away.
